WVILLIAM G. BROWVNE, OF KINGSTON, NElV YORK.

CAN-OPENER.

SPECIFIGATION forming part of Letters Patent No. 654,089, dated July 17,1900.

Application filed Decei'nbi 7, 1899. Serial No. 739,572. (No model.)

To aZZ whom it may concern:

Be it known that 1, WILLIAM G. BROWNE, a citizen of the United States,residing at Kingston, in the county of Ulster and State of New York,have invented new and useful Improvements in Can-Openers, of which thefollowing is a specification.

This can-opener can give a long or sweeping and clean cut and is capableof being used either right or left handed and to out either the top orside of a can; and the inven tion resides in the novel features ofconstruction set forth in the following specification and claims andillustrated in the annexed drawings, in which- Figure l is a sideelevation of the opener. Fig. 2 is a rear or under edge view of theblade or cutter. Fig. 3 is a plan view of Fig 1. Fig. 4 is a sectionalong 0: cc, Fig. 1.

In the drawings is shown a handle or lever at, having a fulcrum orfulcrum end Z) and a cutter or blade 0'. The fulcrum is shown in form ofa curve or rocker extended longitudinally with regard to handle a. Thislongitudinal curve or rocker Z) is continuous or free from interruptionsor humps, so that the handle can swing or rock back and forth whenresting on the fulcrum. This fulcrum is advantageously extended beyondthe cutter, or the free end or point of such cutter, as thereby a longrock or sweep can be obtained, utilizing the entire cutting edge, and atthe same time the handle a gets a satisfactory support orfulcrum-bearing for a long swing or arc. The fulcrum is shown withcorrugations or roughening at d, forming a friction or non-slippingface, so that no displacement of the leveroccurs while the blade iscutting its way through the can wall or top. The fulcrum, besides beinglongitudinally curved, is also curved transversely, as seen in Fig. 4,the roughening d being on this under or transversely-curved face. Theoppositelylocated guards or channels 6, Fig. 4, are formed by offsets orshoulders, and either one or another of such angles or guides 6 beingrun along an edge of the can will keep the knife guided for asymmetrical or neat out.

As the cutter is used either right or left handed one or another of theguides e sits to the can edge. The cutter 0 can be made to out eitherinto the wall or side of the can or into the cover or top. In eithercase one or another of guides 6 will insure uniform distance of thecutting edge from the can edge. The cutter is located centrally to thefulcrum or between the guards or guides e.

The curved fulcrum accomplishes the result of having the fulcrum-pointmove forward or keep ahead of the knife while cutting, while in case ofa single point for the fulcrum the knife gets nearer the fulcrum whilecutting.

What I claim as new, and desire to secure by Letters Patent, is-- 1. Acan-opener comprising a cutter and a lever having its fulcrum providedwith oppositely-located rims having offsets e forming guards or channelssubstantially as described.

2. A can opener comprising a cutter and a lever having its fulcrumprovided with oppositely-located rims having offsets e forming guards orchannels and the cutter located centrally to the fulcrum or between theguards substantially as described.

3. A can-opener comprising a cutter and a lever having an offset rimforming a guard or channel at its fulcrum substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.
